Do You Measure Up? — Dickeson

If we can learn the causes, then engineers, like Buck, or maybe our own clever people, can develop fixes that will stop the stops! These will result in system changes that improve efficiency.

Always hold in mind that our statistical techniques—our bag of tricks—have different rules that apply for their validity. For example, process performance charts (sometimes called XmR charts) work only with historic sequential data—data that hasn’t been sorted for any purpose. But with operation code analysis we don’t necessarily want historic sequential ordering.
